feat(uix): persistence + a11ySemantic + polymorphic core (book §5.3, §6, §9)
Three book canon items codified in code:
**Persistence (libro §6.1)** — separa `hold` (perceptual min) de
`persistence` (lifecycle real):
- New `SignalPersistence = 'transient' | 'untilAction' | 'untilFix' | 'stateBound'`
- New `SEMA_HOLDS_BY_INTENT` canonical lookup table (`src/uix/sema/holds.ts`)
- `EngineSemantic.emit()` returns the resolved signal id; keeps projection
alive past hold for non-transient. Exposes `clear(id)`, `clearTarget(target)`,
`hasActive(id)`.
- `SomaRuntime.trigger()` returns `TriggerResult { id?, persistence? }`.
Exposes `clearSignal(id)`, `clearTarget(target)`, `partRef(part)`.
**a11ySemantic (libro §9.1)**:
- New `MorfoA11ySemantic` (requiresPersistentTrace, requiresLiveRegion,
requiresFocusMove, keyboardEquivalent, reducedMotionFallback) on MorfoEvent.
- `ActiveDom.prefersReducedMotion`: reactive tracker via media query
(`src/arts/adom/reduced-motion.svelte.ts`).
- `ActiveUix.announce(msg, priority?, timeout?)`: lazy-created live region
via `dom.writeNode`.
- `Soma.runtime()` auto-wires `sources.announce`.
- `SomaRuntime.trigger()` honors a11ySemantic after emit (live region, focus,
reduced-motion fallback including `channels: []` for 'state').
**Polymorphic events (libro §5.3)** — ADITIVO sobre shape concreto:
- `allowedFamilies?: readonly SemaFamily[]` opcional en MorfoEventSemantic.
- Provider override via `runtime.trigger(name, { semantic })`.
- Default family of the morfo is implicitly allowed.
- New `SomaRuntimePolymorphicError`.
- New `isPolymorphicSemantic` type guard.
Synthetic `prewriteFixtureMorfo` (src/uix/morfo/test-fixtures.ts) decouples
compile + runtime tests from the production morfo catalogue.
671 tests pass in sema + morfo + soma + adom scopes.
